Advantages & Disadvantages of Secondary Storage
There are many advantages to using secondary storage devices.
Why Storage?
In order for your computer to fully operate effectively, it must have the ability to store data after programs have completed their processing tasks. This processed data is stored in a digital format on either a hard disk, which is called secondary storage, or removable mass storage devices. Primary storage devices is known as random access memory, or RAM, and storage is temporary. RAM has less capacity for data storage and the data vanishes when the computer is turned of
Benefits of Secondary Storage
Secondary storage devices offer several distinct benefits for your computer use, like possessing the capacity to store enormous amounts of information such as hundreds, even the equivalent of thousands, of books. Secondary storage also removes the once-enormous costs to businesses that were incurred for storage of important documents in filing cabinets or storage facilities. In addition, secondary storage devices are safe, reliable and permanent, according to the website University of Rhode Island.
Disadvantages of Secondary Storage
While RAM electronic storage devices are fast, secondary storage devices are slower because they are electro-mechanical. The information on the secondary device has to be first located, then copied and moved to the primary memory or RAM, which is regarded as data seek time, according to the website University of Hertfordshire Department of Computer Science. Also, secondary storage simply provides storage for the computer while, "primary memory, supports ongoing CPU activity by storing instructions and data of currently running programs," according to the website Systems Architecture.
